DependencyInjection fails to inject TagRules to SiteMeshPageExtractor if no TextFilters are defined

SiteMeshPageExtractor has only only constructors that either do not have TagRule[] and TextFilter[] at all or both at once. As result it is not possible for dependency injection to create an instance of the extractor with available TagRule instances if no TextFilter instances are available and the tag rules are silently ignored.

SiteMeshPageExtractor must also have constructors taking only one array type.
